Rig floor equipment: Unconventional casing running system ///

Conventional casing operations usually involve specialized crews and equipment brought to a rig site for the sole purpose of installing the casing. Crews rig up and operate the equipment, connect each section of casing, run it in the hole, cement it in place and are demobilized at the end of the job. All the while, the regular drilling crew plays a secondary role and usually just assists in the process. Keep in mind that this same drilling crew just got done drilling the well by connecting sections of drill pipe and running them in the hole. The idea for a better system came about by asking what would it take for the existing rig crew to run the casing, just like they run every other tubular in the hole?
